. mentsin Steam Driers, .of which the following is a specification.

' ,The main iob 'ect of [this {invention is to ,provideran inn-provedtype of construction for a drying akilnjhaui-ng special features adapted.for zconcentrating the heat in an area above a conveyor belt upon whichthe material 150 be dried-is approximately thru -.the .entire length :ofthe kiln, entering at one end/with its surfaces-an treated conditiomkandexisting atthe opposite end as a completely dried product. I

Another object is lto provide a drying kiln having a novel arrangementof steam coils for generating the heat used in the kiln. This dryingkiln is designed particularly for thepurpose of dryingv a lithographicpaper or the like upon Which a glazing coat such as shellac or varnishhas been applied and is further adapted to completenumeral 10 indicatesthe roof of a relatively 1y dry the varnish on the material in itspassage thru the drying kiln on a conveyor; The above and other objectswill become apparent in the description below, in which characters ofreference refer to like-named parts in the drawing. 7 e Referringbriefly to the drawing, Figure 1 is a side elevational viewof the dryingkiln, showing a portion thereof broken away to illustrate the interiordesign,

Figure 2 is a top plan view of Figure 1, with various portions thereofbroken away to disclose the interior.

' Referring in detail to the drawing, the

long compartment, the shortest possible length for arriving at goodresults being approximately 30 feet. The roof of the kiln 1s oined atits longitudinal edges bysides 11 and 12 and has a bottom 13 whichprovides a relatively long hollow chamber 14 in which the entire dryingapparatus is, housed. The drying kiln is open at both ends and issupported upon st-anchions consisting of angle irons 15 in order toraise the kilnto a convenient position for its use. At one end a'skeleton structure consisting of a post 16' removed some distance fromthe end stan'chions 15 is connected therewith by inclined angle irons 17which form .af'platform on which bearing lugs 18 are; mounted. Thesebearing lugs v.sup-

port. 'aishaft 19 onwhicha vroller .20 is mounted) At one open 'endofthe :drying kiln, a rolleri21 is mounted ona shaft journalled in 'theframework-of the kiln and an endless conveyor belt 22-,is trainedwaboutthese rollers QOPEtIld 21, passing longitudinally thru the drying kilnwhich .receivesfithe material from the feeding platform .provided.bythestruct-ure members 1.6 and 17.

WhQFGtlIGLCODVQ-YOP belt 22 enters the drying kiln, adjacent the'ifeeding ,pl-atform, a pair. of rollers;.23 and'24 are mounted in theframework of the, kiln, one vabove the other ,so thatqthe up perroller23 supports the upper .surface of the conveyor belt 22 while thelower-surface of the conveyor .belt

rides between .both rollersg'23 gander and is;

snpported bytthe "latter. This construction .is necessary inorder topermit the conveyor belt to enter the drying kiln atan inclined planeand then diverge to the horizontal.

Nearthe delivery end of the drying kiln and beside the latter, a boiler25 or other means of generating steam is mounted on a base 26. A steamdelivery pipe 27 extends from the boiler toward a position intermediatethe length of the drying kiln and enters into the chamber 14 of thedrybelow the conveyor belt 22, two sets of delivery manifolds 29 aremounted in a suitmg kiln thru pipes 28. Within the kilnparallel at aninclined plane toward the outer ends of the drying kiln and terminate inreturn manifolds which commumcate with each other thru a steam returnpipe 7 33, which has an outlet pipe 34 connected thereto, the latterleading directly to the boiler 25.- p

The material with whichthis drying kiln is to be usedis paper or thelike, coated with varnish or shellac which must be quickly dried. Thesesheets of material after being coated with a given substance are laidupon the conveyor belt 22 on the feeding platform comprised of themembers 17 and 16. This conveyor belt is actuated by a source of powernot shown on the drawing and slowly passes into the drying kiln,extending thru the entire length of the kiln and conveying the materialthereon thru the kiln to the opposite end of said kiln where it isdelivered in dried condition. ing from the steam pipes 30 passesupwardly, heats the conveyor belt, and circu lates into the chamberbetween the upper kiln in order to serve as drains for the condensedvapor in the coil system, which vapor enters the return pipe 33 and isdelivered to the boiler 25. r I

We claim p 7 1 1. A drying kiln'comprising a longitudinal body open atboth ends, coils in said kiln extending from the center to the open endsof the kiln, and a conveyor passing thru said kiln.

2. A drying kiln comprising a longitudinal body open at both ends,rollers at said open ends of the body,'a platform formed at one end ofsaid body supporting a roller thereon, a conveyor belt passing over theplatform entirely thru the drying kiln, a boiler exterior of said kiln,and coils in said kiln connected to said boiler;

3. A drying kiln comprising a longitudinal body open at both ends,rollers at said The heat radiat-' open ends of the body, a platformformed at one end of said body supporting a roller thereon, a conveyorbelt passing over the platform entirely thru the, drying kiln, a boilerexterior of said kiln in said boiler comprising manifolds mutuallyspaced apart, pipes connecting saidmanifolds, said boiler communicatingthru pipes with adjacent manifolds, and a return pipe connecting'theopposing manifolds with the boiler.

4. A drying kiln comprising a longitudinal body open at both ends,rollers at said open ends of the body, a platform formed at one end ofsaid body supporting a roller thereon, a conveyor belt passing over theplatform entirely thru the drying kiln, a

boiler exterior of said kiln, coils in'said boiler comprising manifoldsmutually spaced apart, pipes connecting said manifolds, said boilercommunicating thru pipes with adjacent manifolds, a return pipeconnecting the opposing manifolds with the boiler, said coils beinginclined from. the center to a lower level outwardly toward'the openends of the kiln to drain the return pipes.

In testimony whereof we affix our signatures.
